Heat Dissipation System

The cooling system of the CloudEngine 6800 series switches uses front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used.

Front-to-back airflow: Power modules and fan modules with front-to-back airflow are identified by . Air flows into the chassis from the power supply side and is exhausted from the port side, as shown in Figure5 Front-to-back airflow for port-side exhaust (using a CE6863 chassis as an example).
Back-to-front airflow: Power modules and fan modules with back-to-front airflow are identified by . Air flows into the chassis from the port side and is exhausted from the power supply side, as shown in Figure6 Back-to-front airflow for port-side intake (using a CE6863 chassis as an example).

Figure 4-57 Front-to-back airflow for port-side exhaust

Figure 4-58 Back-to-front airflow for port-side intake

The airflow direction of the power modules and fan modules required on the CloudEngine 6800 series switches depends on how the device is installed in a cabinet. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If a switch is installed with the power supply side facing the front and the port side facing the back, the switch needs to adopt fan modules and power modules with front-to-back airflow.

Power modules and fan modules using forced air cooling on a switch must have the same airflow direction. If a switch adopts power modules with back-to-front airflow, the switch must use fan modules with back-to-front airflow as well.
